12" Claims.

This invention relates. torecord players andA morel particularly to a record player of the socalled automatic type.

The present invention contemplates a structure wherein` a. rotatablev turntable.y is provided with means for. supporting records in a` stackv above the turntable and dropping them one by one onto: theiturntable. The records are supported by a stationaryv spindle located at the center of theturntable which is provided with a shoulder for engaging the unplayed records adjacent the center holeand. by aside supporti-atthe edge,

ofthe turntable for-supporting: the records acl-- jacent theiredges. The. side support also has anejector for engagingv the bottom-most record ofthe stack andislidingit off its supports, allowingit to droponto theturntable in playing position..

It also. contemplates means, cooperating` with the foregoing in timed relation thereto, tok

move the tone` arm outof the way when the recordis dropping. Y

Although mechanisms oi the general class describedhave heretoforebeen contemplated, there have. beennumerous disadvantages inherent in the previous structuresv which` it. is: coneaof. the. purposes of the present. invention to overcome.

Previous-structures were relatively complicated.

requiring a .considerable number` ofr partsv which were fexpensive .to` manufacture;

service well as` diliicult4 to` properly adjust for handling of the records.

Ones particular disadvantage: ofthe` prior. art wasthatthey werenearly always placed in the hands -ofperscns inexperienced in the mechanical Prior. machines of, this character` were difficult. to maintain in matters andiwh-odid `not understand their operation;. and therefore, were easily thrown out of` adjustment or'brokenfbecauserof the carelessness in *which they were handled.`

-By the present inventionI `haveprovided a record changer which is extremely-simple in its operation, hasbut a few moving parts, and where theiadjustment' for itsioperation isv sosimple as to make itpossible Vfor it tobe .adjusted to properlyhandle the-recordsby persons with relatively little experience; Stillanother advantage of the present device is that its construction is such that no matter how it is. handled it is practically impossiblefor` a person, without deliberate in tention, todo anything during the normal course of operation which will disturb its adjustment or` render the-same inoperative. Becauseof its smplicity, it is economical to manufacture.

l Furthermore, by the presentinvention the handling .of the `record is eiect'edlin sucnamanner `2` that relatively large tolerance of thickness may be allowed and still the functioning of. the" apparatus to'handle the record is not affected.`

Ano-ther advantageresides in the ability of the.

machine to handle warped records, and the construction is such that it is substantially impossible for the machine to break the records..

Still otheradvantages ofthe invention and the:

invention itself will become moreapparent from the .follow-ing description of an embodimentthereof `whichdescriptionis illustrated by the accompanying drawings and forms al part of this speciiication.

Referring to the gures of the drawings throughout which like parts have been designated by like reference characters and particularly to Figs. 1 and 2 there is shown a base IFJ which'is depicted in the drawings as being made of wood. The base. however, can be made of metal or plastic. The device about to be described is so constructed that it can be installed in existing Vcabinets by providing a Vrelatively simple opening therethrough. A turntable II is provided,

being supported on a spindle I2 which spindle is mounted in bearings I 3 and I4 in a support memberIE. A thrust bearing I6 is interposed between the hub VI for the turntable and the top of the housing I5. The turntable isdriven by a motor l V8 which drives a rubber-rimmed idler wheel, not shown, disposed in engagement with the inside of the rim 20 of the turntable. The drive to the rim is well known to those versed in the art and nofurther description thereof will be necessary. Other drives than that shown may be used however with edual effectiveness with the invention. One such drive contemplates a direct or gear connection to the rotatable spindle I2.

vA stationary spindle 25 is provided and may be of the type and structure disclosed in my copending application. Serial No 493.242. led July 2.. 1943. now Patent No. 2.498.333. issued February 21 '1950. The stationary spindle extends through the hollow spindle I2 which spindle is provided with bearings or guides 2S and extends through the bottom of the housing I5. being held immovably therein by a nut 21 disposed on the threaded e'nd 25a. The stationary spindle extends upward from the turntable coaxial therewith. being pro- Y vided with a guide portion 28 for guiding the records onto the turntable. Theupper end is nrovided with a shoulder 29 upon which the stack of records may rest. It also has an offset stackhlding portion 30 for holding the unplayed records, in which is slidably disposed the leaf 3l for 4 holding the records in their proper alignment on the stack, the structure of which is more clearly described in the aforementioned copending application.

The support for the edges of the records, which really supports the records in a zone at their edges, is disposed to one side of the turntable and comprises a pedestal 35, as best shown in Figs. 3 and 4, which is Yprovided with a peripheral flange 33 that engages the top of the base IEI. The flange is provided with openings through which screws or bolts 38 may extend for securing it to the base. The upper end of the pedestal carries a head 39 which incloses the ejector mechanism and record support and which will hereinafter be more fully described.

The pedestal is provided at its lower end with a portion 40 which supports the tone arm carrying mechanism, and the tone or pickup arm III is disposed on its supportingmechanism between the base 4i! and the ejector head 39. Y

It is believed that a short description of the general operation of the device at this point will `materially assist in a better understanding. The unplayed records are stacked on the spindle and the ejector support and one of the records is released to fall on the turntable. The manner of its release will hereinafter be more fully described. As the record'is played in the usual manner the tone arm traverses the record towards the stationary spindle until it finishes playing the record and reaches the runout groove in the center of the record. At this time the record changing mechanism is tripped, which causes the tone arm to be; iirst, raised from the record; second, swung laterally clear of the record to one side of the turntable; third, a new record is ejected from the stack and drops upon the last played record; fourth, the tone Varm is swung inward to the proper playing position; fth, the tone arm is lowered gently onto the record into the start of the playing grooves, which ends the record changing cycle. The newly Vdeposited record is then played until the tone arm again reaches the runout groove, after which the cycle is repeated.

The changer contemplates an assembly which may be assembled prior to installation n the base l0. The spindle support I5, as best shownV in Fig. 4, is substantially rectangular in formation, being generally hollow and provided with top,

Y side and bottom walls carrying the aligned bearings I3 and I4 -for the rotatable spindle which is journalled in the bearings. having a serrated surface is secured to the spindle adjacent the lower bearing. The serrated surface provides for a good frictional engagement with the eccentric wheel carried by the cam slide hereinafter more fully described. The housing is also provided with a pair of bosses 46 (Fig. 4) in which are secured rods II'I that constitute a supporting frame and Vways for the cam slide and its associated mechanism. 'The rods extend from the housing I5 in spaced horizontal parallel relation and are secured to legs 48 which extend downward from the base of the pedestal V35. The rods are Vseated in semi-cylindrical grooves 49 disposed in the bottom of the legs and held therein by screws 5S that extend through the rods into the legs. The pedestal andthe housing I5 are thus connected in properly spaced relation to each other and as previously stated the rods provide a bed or ways for supporting the cam slide mechanisrn.

lThe means for effecting the changing of the record comprises a cam slide, slidably jornalled on A drive hub 45 abscesses Y the rods:` andf'carrying'thelcams for?engagement` with the .t'onearm andfor. operating ithexfrecordf; eecting'; mechanism.: rIhis slideeisleoperated byithel movement: of awheelrwliich. is'eccentrically car# riedxtlierebyandfwhichhas a rim for engagement` withftheserratedthub The sli-de Acomprises a plat'e 55 suspendedxfrom. brackets `an'd'fil :that areslidabl'y journalled on".` t'li'erodslt'l.'

Vjournalled in the sleeve 95, the lower end of the 7, A tone'armlifting rod |03 is slidably rod being rounded off at |05 and adapted to slide on the upper surface of the slide 55 when the slide is moved. The rod |03 extends upwardthrough the sleeve 95 and is provided with an angularly extending portion 04 which extends out through a slot 95 in the sleeve 35. The tone arm support bracket 91 is provided with a vertically extending wallY I l that has a slot |36 through which the part |54 of the rod |03 extends. The part |04 is adapted for engagement with an adjustable stop |06 disposed in a boss |09 on the underside of .the tone arm. .During operation, the slide 55,"in its movement toward the right as viewed in the gures, causes the rod |03 to ride up the cam surface 59, causing the rod to be raised. The end |04 engages the adjustable abutment |58 on the underside of the tone arm and raises the tone arm which pivots vertically about the pivots 9S. On the return movement of the slide, .the rod |03 rides down on the lower p0rtion 60, lowering the tone arm.

The sleeve 95 being'connected to the tone arm is rotated with the tone arm, that is, when the tone arm traverses the grooves the sleeve is rotated clockwise. The lever |0| secured to the sleeve 55, as previously stated, fullls a dual purpose. It is provided with an arm 2 which Vis contacted yby a member carried on the slide 55 to initially rotate the sleeve and hencethe tone arm to move the tone arm to one side of the turntable. The other arm of the lever is provided with a portion which extends outwardly at an angleslightly greater than 90 and then is oiset downwardly at ||3 and is provided with an end ||4 which is pivotally connectedY at |5 to the trip'link TI. (See Figs. 11 and 12.) The trip link Fig. 4, comprises two parts, Tl and 11a, the part 'Via being provided with upwardly extending flanges 'llb between which the end of the link rides. The

link 'l1 is provided with an upwardly extending lug ||6 while the portion 'Ha has a similar lug The two lugs are connected together by a screw H8, the head of which engages the lug |'6 and the? end of which is threaded into the lug A spring 9 is disposed around the screwv ||8 engaging the two lugs ||6 and Thelength of the link may thus be readily adjusted and the connection between the two parts permits the parts to telescope relative toeach other to adjust the position of the pin which carries the roller 'l5 in the slot 18. The part 'l1 is provided with a slot and a rivet |2| is secured inV the part 17a and extends upward through the slot, the end being provided with a head which engages the upper surface of the part TI to retain the two partsin proper position.

It will thus be seen that when the tone arm is rotated that movement is transmitted through the lever ||4 to the link 1l, the end of which is reciprocated in the slot 'i8 opposite the abutment l5 on the eccentric wheel El.

The sleeve 95 extends upwardly through an opening in the top of the tone arm, and carries on its end the ejector operating lever. The operating lever includes a collar |24 which is secured to the sleeve by a screw and carries a lever |26 having an upstanding lug |21. (See Fig. 5.)

The tone arm is raised, as previously stated, by the rod |03 riding up the -inclined portion 59 of the slide. The swinging of the tone arm after being raised is also affected by the slide. The slide carries a tone arm moving member or cam which comprises a plate |30 having a pair of 8 elongated slots |3|, which enables the plate to be secured to the 1underside of the slide by rivets |32. The plateis provided with an upstanding side wall which carries a lug |34 having a substantially vertical edge or cam face |35 adapted for engagement withthe edge of the lever ||2. A spring |36 connectsto the slide 55 at |37, Fig. 4, and to a lug |38 on the bottom of the plate. In this manner the plate and its lug |34 are resiliently held on the slide, the ends of the slots |3| bottoming against the rivets |32. Movement of the member relative to the slide is permitted when the force exerted.

against the vertical edge |35 by the lever ||2 is great enoughV to overcome the tension of the spring |36. This permits theV tone arm to be moved even when the lug |34 is in engagement with the lever H2, the spring |36 allowing the member to slide on the cam slide 55 by reasonof its mounting. VDuring normal operation, when the cam slide is moved toward the position ultimately reached as illustrated in Fig, 13, the lug |34 engages the lever ||2 and rotates the sleeve 65. This swings the tone arm counterclockwise clearof the turntable to permit the succeeding records to be dropped without hitting the tone arm. The rotational movement of the sleeve also carries with it the lever |26 which operates the ejector mechanism about to be described.

The pedestal 35 is provided with a seat |40 on which the ejector head is secured. The headV comprises a base |4| which, as best shown in Fig. 5, is of a rectangular shape, being provided with a down-turned ilange |42 at one end and an up-turned flange |43 at the other end. The flange |42 is secured in the seat |40 by screws |44, which also secureV a plate |45 coincident with the ange |42 to the seat. The plate |45 and the ange |42 could be made in one part if desired. The plate |45 is provided with upward- 1y extending portions |46 having apertures |41 which are in alignment with apertures |48 in the flange |43, These apertures are adapted `to receive rods |49 which may slide therethrough and provide means for supporting and guiding the remainder of the head. The plate is alsol provided with a square aperture |50 adjacent the" is of generally rectangular formation having aV curved record engaging edge |56. The plate is provided with lugs |51 and |51" struck down-y ward from the body of the plate and'provided with openings through which the rods mayslide, the plate thus being slidably mounted on the rods. Secured rigidly to the ends of the rods by screws |58 is a plate 59; the screws extend through the plate and are threaded into the rods |49. As can best be seen in Fig. 6 the bottom portion of the plate |59 has struck therefrom and bent inward- 1y two lugs lee and 15|. The plate |55 is pro-5 vided with a downwardly extending lug |62 and a helical spring |63 is connected between the lug |62 and the lug |60 thus pulling the plate |55A on the guide rods |49 against the plate |59. The plate and the rods |46 are slidable'on the as best shown in Fig. 14,v

Interposedibetween the Vbosses :gissatse |90 and 200 is a flat spring 201, the'spring may 'be set in undercuts in the bosses |90 and 200. Thespring bridges the slot |83 and the lever |84 .isprovidecL above the lug 205, with a notch 2|0. -In the position shown in Fig. 16 the lever is tending to be rotated by the end of the spring 202 bearing against the point 20|. Further rotation is prevented, however, 4by the spring 201 the end of which engages inthe notch 2|0. The further rotational movement of the lever |84 against the pressure ofthe spring 201 in the notch 2|0, causes the spring to bow downwardly as shown 'in'Fig 1'?, allowing the lug 205 to engage the lateral extension 203 'of the lever |92 and rotate it counterclockwise lifting the end |96 01T of the ,lever' |13. When this occurs the spring |10 forces vthe levers |65 and |13 upward, disengaging the 'part '|66 of the lever |65 from the hole |5| or |52, wherever it happened to be engaged at that time,Y andV releasing the slide so that it may be 'moved to its alternate position. This also pivots vthe lever |13 so that the ends |11 and |18 are 'free from engagement with'the lug |21 on the 'head |24, and the head may be freely slid to its alternateposition.

` It will be noted that the movement of the tone arm to oneside of the turntable is effected by the member |34 which engages the lever ||2V -lcarried by the sleeve 05. It will also be noted that the rotation of the sleeve causes the collar" |24 and its associated lever |26|21, to also be 'rotated in counterclockwise direction. As previously stated the lug |21 is adapted to engage either one of the tongues |11 or |18 depending f upon the relative position of the plate and car.

lriage |55 on the ejector bed |4|. This engagep ment is effected after the tone arm is raised and swung suiciently far to one side of the turntable to allow clearance space for the frecords to be dropped. The member |34, however, moves the lever V|`|2 farther than is necessary to f` effect clearance' space for dropping of the recordsv fand this additional movement is utilized to effect the release of a new record from the stack onto the turntable. Just before the cam slide reaches the limit of itsmovement, the lever |21 engages 'with one of theftongues |11 or |18, depending on the position to which the head is set. Continued "movement of the lever |21 slides the'slide |55 against the pressure of the spring |63 away from the'plate'. |59 (see Fig. 8) onthe rods |49, the 'curved end |56 of the slide sliding through the slot |81 and engaging the edge of a record to shove it off of the shelf |80. Y

Y This movement, yso far described; is effected: positively by the lug |34 contacting the lever |2 "on'the sleeve 95. The return movement of the arm is effected by the ejector; the spring |63 j'pulls Vthe plate |55 back toward the abutment Y plate |59, Vand this Ymovement is transmittedfrom the'tong'ue |18 or |11 through the lever i sition because of the Vaction of the ejector slide,

means isprovided to prevent overtravel of the tone armV and jumping of the needle in the "grooves as it is lowered. This means is best y shown in the bottom plan view inV Fig. 22 and the fend view in Fig. 23 and is effected by means of a vlaver 22|! Whichissecured to the rod |03 above the'endl |05. VThis'lever rotates wit-htherod |03 which rod rotates with the sleeve 95. The lever is provided with the upstanding pin 222. Securedon a boss 223, on the sideof the housing 35, is a lever 224 (Fig. 22) of thin flexible metal. This lever is disposed above the path of travel ofthe pin 222 on the rod, Ywhen the tone arm is in its normal playing position. A spring 225 connected to the end of the lever andY tothe other side of the housing, pulls the lever tov/ard and against'the bearing sleeve 94, which limits the movement of the lever. As the tone arm moves in while` playing a record, the arm 220 is moved counterclockwise as viewed in Fig. 22, until it ultimately reaches the position atthe end of the playing of the record, shown by the dotted lines, where the pin 222 isdirectly under the lever 224. Whenrthe slide raises the rod |03 the pin 222 and the'lever 220 rise with the rod and the end of the pin engages the underside of the flexible lever 224 which bends upward. It will be remembered that this occurs as the first movement Vof the cycle when the pickuprarm is lifted off of the record. As the movement of the cycle, the pin 222 which is -traveling in an arcuate path, now clockwiseas viewed in Fig. 18, slides across the under surface and slips off the edge of the lever 224, allowing the lever to spring back ,to its normal position to one side of the pin, which is on the side in the path of travel of the pin 222 when the tone arm is moved inward after ejection is eiected. This is furthervshown in full lines in Fig. 22. A spring 226 is disposed about the rod 03 between the arm 220 and the lever 0| assuring that the rod |03 and its attached parts returnto their lower position. When the ejector spring returns the tone arm to the approximate playing position the pin 222 engages the edge of the lever 224, moving it against the pressure of the spring 225, this spring being weaker than the spring |93 in the ejector head. This holds the tone arm from accidental overtravel which `might otherwise occur due to the fact that lug |34 is no longer in contact with the lever ||2 and assures that the tone arm will be lowered into its proper position in the record playing groove.

In operation a plurality of records are stackedV on the spindle 25 the upper offset portion 30 of the spindle extending through the holes and the lowermost record resting on the shoulder 28.

The edges of the record rest on the shelf |8801' the ejector. One record is ejected fromA the stack to place the same on the turntable by the Y simple expedient of lifting the tone arm and i the Vopening |5|. VLowering of Ythe leverV |84 causes the ejectorV to be locked into the proper position. The ball onV the lever |84 engages the uppermost Vrecordof the stack and holds A'-thfe. vrecord on the support against accidental dis-Y placement. The recordA playingV is started by energizing the motor |8 which drives the turntable to play the record' which is reproduced in any well known manner by means ofthe pickup and an amplifier. Y

When the,V needleereaches the Vrunout u groove near the center of` the record, the tone arm .willV have moved toward the spindle, from the position shown in Fig. 11, to the position shown in Fig. 12. At this time the trip roller i6 is withdrawn from engagement with the lug '.'5 on the eccentric wheel, and the spring 83 causes the wheel to be rotated with its periphery into engagement with the serrated driving hub 45. Since the wheel is rotated by the rotating hub 45 and is eccentrically mounted, the slide will be moved in the direction of the arrow 93 in Fig. 12. As the slide 55 is moved to the right, as shown in Fig. 4; the-cam surface 59 engages and raisesV the rod |03 which raises the pickup arm. At this'time the pin 222 hits against the lever 22e bending it upward. Further movement of the slide to the right causes the face |35 of the upstanding lug itil on the slide l 3e to engage with the lever H2, moving the tone arm outward counterclockwise free of the turntable. As the pickup arm is moved outward; the lever 26 on the sleeve 95 is also moved, the lug |21 contacting with the tongue |18 on the lever H3. This lever, being'connected to the ejector slide, moves the slide outward through the slot |81 until it engages the edge ofthe record and shoves it on the spindle shoulder 29 and the shelf |35. Thereupon the record drops down onto the turntable into playing position. By this time the eccentric wheel has reached its lfarthest position asY shown in Fig. 13, where the slide is moved to the limit of its movement and thespring 85, which holds the eccentric wheel against the hub 45. attains its greatest degree of compression. Continued movement of the wheel causes the slide to be returned towards the original posi.- tion by the spring Se, withdrawing the lug ld from contact with the lever. H2.

During the extremity ofthe movement. the position taken by the parts in the ejector head is as shown in Fig. 8, where the ejector slide had moved on the rods M9 against the pressure of the spring li away from the plate |59. When the member IM moves away from the lever H2, the ejector slide is released and the spring |53 pulls the slide baci; to the positon shown in Fig, '7.

This pressure is also transmitted through the ...y

tongue H3 and lever |26 to the sleeve 95 rotating the tone arm toits playingposition above .the turntable. As previously stated the pin 222 had slipped out from underneath the lever 22s and the le-Veris now in the return path of the spring, pressing against the pin 222, preventing overtravelfof the tone arm by the-action of the lslide and assuring that it will notmove inward an indeterminate amount due to inertia. The

eccentric wheel continuesits rotation, the slide returning in its travel, until the rod |il-3 slides down the cam 59 onto the lower portion 60.; at this time the pin 222is withdrawn from contact with the lever. 122!` and the tone arm is lowered gently onto the recordyin` proper playingposition.. The record is then played, in; the manner previously described, until itv reaches the runout groove whereupon this cycle is repeated.

In the eventthat it is desired to play 12-inch records the ejector mechanism is moved from the'position shown in Figs.- 7 and Sftothe position shown inflige. e and 10.1 Thisiseiected-byfraising t-helever |35 which causes the disengagement ofa'the lever |55 from the hole ll, lafter which the housingirnay ber slid rearwardly', the lever mi.

'releasedand the lug |66 is thenengagedginthe opening |52and the mechanism is then located inpositionrfor. playing 1.2-inch` records.

Itwill-befnoted that the ejector head-justdescribed is; Operated. by lifting the; 'leven |84. and

sllding't'he headtoV the desired' position forfhan-4 dling either 1G or 12-inch records. In Figs; 18 to 21, I have illustrated a modied form of head wherein the-adjustment forl or 12-inchrecords is made by'turning the head 180; This has-certain advantages in compactness, economy and simplicityV of' manufacturing which will becomel apparent as the description proceeds.

Since the mechanism up to the point where the head is attached is substantially'the same, the description will not be repeated. In this instance the xed base plate MI ofthe previous embodimentis replaced by a plate 230 which is of substantially rectangular formation and isprovided with a downwardly bent ange 23| and is secured to the pedestal 35 by screws 232 in a manner similar to that'previously described. Seated on top of the plate 23) is a movable baseplate 233 which comprisesa substantially rectangular flat intermediate portion having the longitudinal sides bounded by flanges 234. This plate'is pivotally secured to the plate 23.8 by a connection which permits the plates to be moved away from each other and from interlocking relation therewith, and rotated 180 to an alternate position. The position shown in Fig. 20 is for playing 12`- inch records. This connection islelected byproriding an opening 235 intermediate the ends of the plate 23o and a similar opening in the plate .253. A stud having a shank 231 extends through the openings and isprovided with. a head 2.38 which engages'A the bottom surface Aof-theplate 23B. A pair of bentspring washers 239 are-dise posed on the shank 231 and a locking ringr2'4 disposed onthe reduced end of. the shank-holds the `washer and stud in position in the pla-tes. the reduced end being staked over'to hold it'. in place; It will beseen that by means of this'connection the plate 233 may raiseupward relative to the plate 2353, the spring washersg23i) Hattening.r out' when the-plate is raised.

Equally spaced from the pivot` point and on diametrically opposite sides in the .plate 230, are provided aperturesZM. These apertures cooperate with-projections `2.43 on the plate 233 to hold the two plates locked together and against movement under pressure of the springs 239, when the plate 233 is resting on the topof the plate 234). It will thus beY seen that when the plate is rotated 180. the'proiections 243 engage with the edges of the apertures 24| and the projections raise out of theapertures the spring 23S compressing.

The sleeve 95 extends upward in alignment with the pivot just described. The end of the sleeve terminates just below the pivot and is provided with an arm Zilli which is movable .below the plate 235| and carries a short lug 2&5 that extends through an opening 2li@ in the plate'` 23|) which opening is of conformation to permit free movement of the pin'Z- therein when the sleeve S5 is moved. The plate 233is also provided-with pair of openings 24'! and 2518. rIhe opening i241 being above the pin` Zliwlien the device is adjust-ed for 12-inch records as shown, and the opening Elli! being abovethepin when-itis r0- tated 180" for playing lQ-inch records. The openings are-oi' sricient size so placed.. to permit the pin toswing therein andto perform the function about to bedescrihed.

The base 233 supports two ejector plates which are each operated by the pin 2.45. The plate' is substantially L-shaped, havingu a curvedsur- 4iace grtior engaging tlieliecord endLbeing-providedlwith three elongatedslots.251.-.w Thisgnlete s held onto the base 233 by rivets 252 extending loosely through the slots and secured in the plate 233. The other plate 253 is also substantially L-shaped being disposed on the other end of the base 233 and secured thereon in a like manner. The two plates are held inward from the edge of the supporting plate 233 and towards each other by a spring 251i secured to the lugs 255 and 256 on the plates 239 and 2,53, respectively.

. The plate 239 is provided with an upstanding lug 251 and the plate 253 with a similar lug 253 disposed on the end which extends adjacent to the sides 234; these lugs are adapted to be contacted by an adjusting screw 259 and 253 respectively, which are threaded through lugs 26| and 252 struck upward from the plate 233, to permit adjustment of the plates and Iimitthe movement of the plates by the spring. This permits a means for adjusting the return travel of the tone arm when a record has been changed to determine it-s position when it is lowered into the playing groove, this portion of the operation being in substance the same as described for the Y preceding embodiment.

The plate 259 is provided with a downwardly bent lug233 which is adapted to extend down- Ward into the opening M1 forrcontact with the pin 245. The plate 253 is likewise provided with a lug 254 for contact with the pin 235 when the head is Y adjusted for playing l2-inch records. The base 233 is provided with pairs of record supporting-projections 266 and 251 on opposite ends,

yeach pair being designed to support a stack of V12 or 10-inch records respectively.

' A cap 235 covers the assembly and may be secured thereto by screws, not shownl which extend through the sides of the cap into the walls 234 of the part 233 or it may have a suitable friction grip therewith. The material of the cap is cut away at 258 and 239 to provide slot-s for allowing the slides 249 and 253 to slide out therethrough and engage the edge of a record disposed on the projections 235 andA 281. The mid-portion of the cap is provided with a rectangular opening 210 having upwardly extending walls 21E on opposite sides. each Wall is provided with a semi-circular notch in which is seated a member 212 which is provided with an oiiset center portion 213. A record engaging holddown lever is xed to the ends of Vthe member 212, which ends extend beyond the walls 211, and comprises a pair of arms 211 which curve toward and meet each other at zii? and carry a ball 213 adapted to rest on the uppermost record of a stack. The front and rear edges of ofthe opening are provided with downwardly 'the lug 263 on the slide 2139, pushing the slide out `in the slot and engaging the edge of the record and pushing it off Vthe shelf The spring 252' I returns the tone arm by pressure of the lug 233 against the pin 2,35 which in operation is substantially the same as that described for the previous embodiment. As previously stated the return of the Vtone arm'can be controlled by the Vadjustment of the screw 259.

When itis desired to play lZ-inch records the cap is v'rotated and the detent rides Vout of the 16 Y apertures and the plate is Vraised 'which come presses the springs 239 allowing the plate 233 to be raised oi of the supporting plate disen gaging the projections 2&3 from the holes Mi, after which the head may be rotated 189 and loweredinto position. ln this case the operation is exactly7 the same as described except that the slide 253 pushes the records oil the sheir` 251.

It should be particularly noted that because of the manner of connection or" the slide i3?! which carries the lug i345 to the cam slide this member having a spring connection therewith, that any interference with the tone arm during the record changing cycle does not tendY to bend, displace or break parts such as heretoiore has been a common occurrence with many record changers.

A still further advantage resides in the :tact

that the ejection or" the records is eiected by if the record was not properly placed on the The mid-portion of the top of supports the spring E35 permits the operating member |341 to slide relative to the slide 55 and no damage is done. In this case the operator will note that the same record is being played twice and can remedy the diiculty. This also applies when the ejector slide reaches the end of its movement. That is,'if the slide reaches the end of its movement before the cani slide has reached the limit oi its movement, this connection permits relative movement between the cam Vslide and the lug i3d without affecting its adjustment.

It should also be noted that because of the tone arm being connected to the sleeve 35 iat it is possible to eject undesired records nianualiy from the supports by simply moving the tone arm to its outermost position which rotates the sleeve 35 and operates the ejector slide.

Y Another feature resides-in the means for coop- Y erating with the tone arm to holdthe tone arm when the apparatus is not being operated to prevent accidentalV damage to the tone arm and its pickup means As best shown in Figs. 1 to 2a,ra bracket 2l .ber having legs 232 and 233 and a connecting Wall 234. As previously Vmentioned thetone arm is capable of independent movement because of the manner of connection with the cam slide. Y

Thereforeit can be lifted and seated, as shown in Fig..2a, on the bracketvat any time. YThe bracket is so oriented relative to therest of the apparatus that when the tone arm is placedV in this non-playing position the springrin the ejector mechanism is exerting a pressure on the tone arm which pressure holds the side of the tone arm against Vthe leg 232 and there is suicient frictional engagement to prevent accidental displacementeven though the'machine is being moved.

It has also been shown that because of the simplicity ofV the mechanism certain` economies in manufacture result therefrom; and that even though simple, the mechanism is extremely sturdy and not subject to the frequent disalignment of parts which makes it necessaryV to call a serviceman to readjust the same. Being small andv compact it is possible to install the same in existing cabinets where, very often, space for installation of an automatic changer is at a premium. Because of the frictional drive and its simplicity, gear noises normally present in record changers are completely elminated and the entire mechanism is extremely simple, smooth, fast and quiet in its operation. Because of the construction and the relatively few moving parts, 1ubrication periods` are infrequent.

Having thus described my invention I am aware that numerous and extensive departures maybe made therefrom without departing from the spirit or scope of the invention,
